Php 对foreach中数组中的项进行分组和求和

我正在遍历两个存储过程的结果集，在一个存储过程中根据另一个存储过程中的字段获取结果

包含结果集的两个数组是

$customers

和

$subcustomers

foreach($customers as $customer)
{
      foreach($subcustomers as $subcustomer)
      {
            if($subcustomer['parent'] == $customer['id'])
            {                        
                  if($customer['innumber'] == null && $subcustomer['innumber'] != null)
                  {                       
                      $chartInboundSub['name'] = $customer['name'];
                      $chartInboundSub['label'] = $subcustomer['innumber'];
                      $chartInboundSub['countInbound'] = $customer['count'];
                      $chartInboundSub['minsInbound'] = ceil($customer['duration'] / 60);
                      $chartInboundSub['customerid'] = $customer['id'];

                      array_push($out['chartInbound'], $chartInboundSub);
                  }
            }
       }
}

print\r（$out['chartInbound']）

的当前输出如下：

Array
(
    [0] => Array
        (
            [countInbound] => 426
            [minsInbound] => 340
            [name] => Telekomm
            [label] => 01-02
            [customerid] => 6
        )

    [1] => Array
        (
            [countInbound] => 1
            [minsInbound] => 2
            [name] => Telekomm
            [label] => 01-02
            [customerid] => 6
        )

    [2] => Array
        (
            [countInbound] => 3
            [minsInbound] => 21
            [name] => Telekomm
            [label] => 080
            [customerid] => 6
        )

    [3] => Array
        (
            [countInbound] => 1920
            [minsInbound] => 15766
            [name] => Telekomm
            [label] => 084
            [customerid] => 6
        )

    [4] => Array
        (
            [countInbound] => 2332
            [minsInbound] => 17521
            [name] => Telekomm
            [label] => 084
            [customerid] => 6
        )
    ...
)

上述结果需要按

名称

、

标签

、

客户ID

与

countInbound

和

分钟Inbound

进行分组，因此：

所需输出应为：

Array
    (
        [0] => Array
            (
                [countInbound] => 427
                [minsInbound] => 342
                [name] => Telekomm
                [label] => 01-02
                [customerid] => 6
            )

        [1] => Array
            (
                [countInbound] => 3
                [minsInbound] => 21
                [name] => Telekomm
                [label] => 080
                [customerid] => 6
            )

        [2] => Array
            (
                [countInbound] => 4252
                [minsInbound] => 33287
                [name] => Telekomm
                [label] => 084
                [customerid] => 6
            )
        ...
    )

---

我认为这应该行得通。我还没有测试代码，所以我没有做出任何承诺

$map = array();
$i = 0;

foreach($customers as $customer)
{
      foreach($subcustomers as $subcustomer)
      {
            if($subcustomer['parent'] == $customer['id'])
            {                        
                  if($customer['innumber'] == null && $subcustomer['innumber'] != null)
                  {                       

                      $key = $customer['name'] . '/' . $subcustomer['innumber'] . '/' . $customer['id'];

                      if(isset($map[$key])) {
                            $out['chartInbound'][$map[$key]]['countInbound'] += $customer['count'];
                            $out['chartInbound'][$map[$key]]['minsInbound'] += ceil($customer['duration'] / 60);
                      }
                      else {
                          $out['chartInbound'][$i] = array(
                                  'name' => $customer['name'],
                                  'label' => $subcustomer['innumber'],
                                  'countInbound' => $customer['count'],
                                  'minsInbound' => ceil($customer['duration'] / 60),
                                  'customerid' => $customer['id'],
                          );
                          $map[$key] = $i++;
                    }
                  }
            }
       }
}

对于

名称

、

标签

和

客户ID

的每个组合，它都会创建一个字符串键，该键对于该组合必须是唯一的。然后检查该键是否已经有任何数据（通过在

$out['chartInbound']

中保留一个单独的键及其索引列表）。如果是这样，它只添加

countInbound

和

mininbound

。如果没有，则将整个

$chartInboundSub

放入

$out['chartInbound']

---

请注意，这取决于密钥的唯一性。例如，如果在名称中允许

/

，则可能不是这样。

而不是使用

foreach

循环，我使用每个PHP数组都具有的“迭代器”

假设数组已排序，则记录“当前组id”的单次传递就足够了

我使用了一种“预读”技术，因此不需要“如果”测试来找出如何处理“当前记录”

守则：

/**
 * Output stored in here...
 */
$output = array();

// groupId consists of:   name, label, customerid

// read ahead - we need the current entry of the source array...
$currentEntry = current($source);

while ($currentEntry !== false) { // process the array / file / resultset etc.

    // start of a group... process the first record that every group has...
    $currentGroupId = getGroupId($currentEntry);
    $currentGroupCountInbound = $currentEntry['countInbound'];
    $currentGroupMinsInbound = $currentEntry['minsInbound'];

    // read the next record as we always 'read ahead' after processing a record...
    next($source);
    $currentEntry = current($source);

     while ($currentGroupId == getGroupId($currentEntry)) {
        // same group = total the values...

       $currentGroupCountInbound += $currentEntry['countInbound'];
       $currentGroupMinsInbound += $currentEntry['minsInbound'];

       // next entry in the input array - will end this group if not the same...
       next($source);
       $currentEntry = current($source);
    }

    // end of the current group -- output the information...
    // add it to an array... or whatever...
    $output[] = array('groupid' => $currentGroupId,
                       'countInbound' => $currentGroupCountInbound,
                       'minsInbound' => $currentGroupMinsInbound);
}

// show the output...
echo '<pre>';
print_r($output);
echo '</pre>';
exit;

// ---------------------------------
function getGroupId($entry = array())
{
    if (empty($entry)) {
        return array();
    }

    return array(
        $entry['name'], $entry['label'], $entry['customerid']
    );
}

对不起，我真的不明白，当名称、标签和customerid相同时，您想对

countInbound

和

minInbound

求和吗？@PHPeter:是的，这是正确的

Array(
    [0] => Array(
            [groupid] => Array(
                    [0] => Telekomm
                    [1] => 01-02
                    [2] => 6
                )
            [countInbound] => 427
            [minsInbound] => 342
        )

    [1] => Array(
            [groupid] => Array(
                    [0] => Telekomm
                    [1] => 080
                    [2] => 6
                )
            [countInbound] => 3
            [minsInbound] => 21
        )

    [2] => Array(
            [groupid] => Array(
                    [0] => Telekomm
                    [1] => 084
                    [2] => 6
                )
            [countInbound] => 4252
            [minsInbound] => 33287
        )
)
